Experience reliable everyday connectivity with the ZTE Blade A51, featuring a Unisoc SC9863A octa-core processor, 2GB LPDDR4X RAM, 32GB or 64GB eMMC 5.1 storage, and a generous 6.52-inch IPS LCD display with 720 x 1600 pixel HD+ resolution, all packaged in a compact design measuring 166.5 x 75.6 x 8.5 mm and weighing just 173.7 grams. This certified refurbished smartphone from Reboot IT delivers essential smartphone functionality at an exceptional value, perfect for staying connected without breaking the bank.

The large screen makes it excellent for video calls with family and friends, whilst the dual camera system captures everyday moments. It's particularly well-suited for first-time smartphone users, students on a budget, or as a reliable backup device for work and travel.
Key Features and Benefits
The 6.52-inch display provides ample screen real estate for comfortable viewing, making everything from web browsing to video streaming more enjoyable. With 4G LTE connectivity across multiple bands and dual SIM capability, you'll stay connected wherever you go. The device includes modern conveniences like NFC for contactless payments, USB Type-C charging with OTG support, and a rear-mounted fingerprint sensor for quick, secure access. The 13MP dual camera system with LED flash and HDR ensures you can capture clear photos and 1080p video, whilst the expandable storage supports up to 128GB via microSD card, giving you plenty of room for apps, photos, and media.

Operating System Considerations
Running Android 11 (Go edition), this device benefits from an operating system specifically optimised for efficient performance on entry-level hardware. The Go edition launches apps up to 20% faster whilst consuming less data and storage space, making it ideal for budget-conscious users. However, it's worth noting that the Go edition includes lightweight versions of Google apps with some feature limitations, such as restricted multitasking and the absence of split-screen functionality, in order to maximise performance on devices with 2GB RAM.
Understanding Refurbished Grades
At Reboot IT, we offer two cosmetic grades to suit different preferences and budgets. Excellent grade smartphones appear virtually like new with only very minor wear—screens may have light, shallow scratches that won't catch on a fingernail, and the body shows minimal signs of use. Good grade devices are fully functional and tested but display more visible signs of previous use, such as body scratches, possible small paint chips, or light screen scratching from regular wear. Regardless of grade, every device undergoes the same rigorous testing process to ensure complete functionality.
Verified Reboot Refurbished Quality
Every ZTE Blade A51 sold by Reboot IT has been meticulously tested across all features and functions to ensure it meets our exacting standards. Our comprehensive testing process evaluates every aspect of the device, from screen responsiveness and camera quality to connectivity performance and sensor accuracy. Since 2001, Reboot IT has been an industry expert in refurbishing technology, utilising cutting-edge diagnostic software and thorough testing protocols to verify each unit's performance. All devices are verified refurbished through Reboot IT's rigorous multi-point inspection process, ensuring you receive a smartphone that performs reliably day after day.
